Definitions

  • the invention relates to a method for operating a storage system for persons according to the preamble of the main claim.
  • Such storage systems are used in particular for bedridden, recumbent patients who are at risk of pressure ulcer complaints and such air-insufflated systems are already known from practice.
  • These air-insufflated systems can also have different air chambers in order to be able to set the chamber internal pressure to the respective patient weight.
  • the invention has the object of providing a patient support system in such a way that with ease of use and low cost a very good pressure reduction on the patient's skin is achieved in order to significantly reduce the pressure ulcer risk.
  • a method of operating a storage system which does not attempt to form an optimal but static internal chamber pressure of the storage system, because this optimum static pressure is very difficult for caregivers to find out and, moreover, this optimal internal chamber pressure changes immediately if the patient z. B. moves to another posture.
  • the invention is based on the consideration that the chamber internal pressure of the storage system is exposed to a permanent change between an upper and a lower internal pressure value and this change of internal pressure of the optimal pressure for the individual patient is passed through and the time in which the chamber internal pressure either is too high or too low for the patient, is sufficiently short, so as not to cause the risk of bedsores. In particular, gross incorrect settings of the storage system are not possible.
  • the chamber internal pressure is successively increased and / or reduced, in order to increase the optimum (even when increasing (reducing) the chamber internal pressure on the one hand to undergo individual internal pressure for the patient and to take some time in passing through this ideal internal pressure.
  • This passage of the chamber internal pressure from the lower base value to the upper value and vice versa can take place in several stages as well as in an advantageous embodiment completely continuously, to obtain by this continuous pressure change in any case the ideal chamber internal pressure at least for a certain period of time, so that a essentially sinusoidal change in the chamber internal pressure results.
  • the upper value and the basic value can be preset depending on the patient weight and patient size. In a practical embodiment, this means that z. B. the nursing staff in the default setting only has to consider whether a light or heavy patient is on the storage system.
  • the storage system may consist of two or more chambers, which may have a different chamber internal pressure, thereby enabling a particularly good adaptation to the patient.
  • the air pressure in the mattress is 40 mbar. Only between the buttocks and the mattress, a contact pressure of 25 mmHg is measured. At all other so-called preselection points, the contact pressure is> 25 mmHg.
  • the air pressure (general pressure) is now continuously reduced within a certain period of time until it has reached the value of 20 mbar. When the air pressure drops below 5 mbar, a contact pressure of 25 mmHg is measured under the shoulder blades, while the contact pressure under the buttocks becomes> 25 mmHg.
  • a storage system 1 which has the size of about a mattress and consists of several juxtaposed chambers 2.
  • the storage system 1 is therefore suitable for lying or bedridden patients.
  • a storage system according to the invention can also be designed for, for example, sitting patients in the form of a wheelchair cushion or the like.
  • the chambers 2 have an interior space which can be filled by a filler in order to build up a chamber internal pressure.
  • This filler may advantageously be air, but also other suitable gaseous or liquid media.
  • the chambers 2 may be filled with other fillers, for. As foam, in addition to z. B. air is supplied to change the hardness.
  • the chambers 2 may be covered by a support 3 to the top of the storage system 1, on which the patient lies.
  • a pump motor 4 can generate the volume of air with which the chambers 2 are filled.
  • the engine 4 pumps in an advantageous design 4 - 6 l / min. and builds up a pressure of up to 200 mbar.
  • the pump motor 4 is connected via a supply line 5 with a solenoid valve 6, which can be switched to two different positions. In one position, a maximum pressure of 40 mbar at the outputs A, B and C, in the other position of the solenoid valve 6, a maximum pressure of 20 mbar is generated.
  • the pressure regulation is done by appropriately installed pressure relief valves, which are controlled by the position of the solenoid valve 6.
  • the mentioned pressure values are given by way of example only, as well as the number of outputs and can of course be varied.
  • a first control valve 7 is achieved, which ensures that the chamber internal pressure z. B. in the first switching position of the solenoid valve 6 from the upper pressure (40 mbar) to the lower base pressure (20 mbar) drops, then rise again to 40 mbar.
  • the upper pressure to 20 mbar and the lower base pressure to 5 mbar are set.
  • the increase of the chamber internal pressure from the basic pressure to reach the upper pressure can, for. B. in 10 minutes, in a uniform pressure increase over these 10 minutes, this value is of course only one embodiment and can be changed depending on the application.
  • a pressure sensor 8 measures the air pressure throughout the system and detects deviations. In a permanent pressure drop, for example, optically z. B. be alerted by a warning lamp or acoustically by an audible alarm on the malfunction.
  • a second control valve 9 controls via the corresponding channels A, B and C different chambers 2 of the storage system.
  • the control with regard to the minimum pressure is passive in the present exemplary embodiment. This means that at a greater force on the storage system or its chambers and the venting stronger and thus the minimum pressure can be correspondingly lower. At a lower force, these described conditions are reversed.
  • the related electromechanical components can also be replaced by electronic components, with the control valves 7 and 9 related electromechanical / pneumatic components represent there.
  • a control disk is moved, which is arranged opposite a fixed control disk.
  • the control discs are ground flat on their contact surface and a spring pressure both control discs are pressed together so that no air can escape between the control discs.
  • Both control discs are provided with holes. Stand the holes in front of each other, the air is passed on via the supply line 5 accordingly. By turning the control discs, the holes move and thus close the airway.
  • This air control could also be realized by electrical valves that can be controlled by a specific software.
  • the chamber internal pressure of a chamber thus continuously passes internal pressure values between the upper and the lower limit value, and a sinusoidal curve-shaped formation of the internal chamber pressure between the upper and lower limit value can result.
  • the different chambers 2 may have different cycles in order to obtain an ideal adaptation of the storage system to the patient.
  • the invention is therefore applicable to so-called alternating pressure systems, because even with these systems can, for. B. the higher pressure in turn not be formed statically, but to assume an Optimum value fluctuate around and the same can possibly also be done at the lower pressure of a pressure change system.
